DUCT ARMOR FOR RESIDENTIAL AIR DUCT REPAIR
Problems we have found inspecting in ground duct work:
· Rusted galvanized metal
· Water damaged sonotube that is falling apart & blocking air flow
· Exposed raw earth
· Rodent and termite destruction in the air system
· Air leakage
· Mold, mildew and fungus growing in the duct work
· Musty damp odors
Under slab/in ground duct work in West Texas is largely composed of sonotube which is a cardboard product. With time and normal or elevated subsoil moisture, the cardboard deteriorates, cultures mold and fungus and can leave exposed earth in the system. Termites love to secretly feed on damp cardboard. The galvanized metal transitions rust and leave the system exposed to particles not meant to be breathed or dispersed throughout in the air conditioning system and living space of your home.
The Duct Armor® process clears the air flow system of debris and coats the system with our patented and proprietary Duct Armor® product which is 50 % adhesive and has a high zinc content which inhibits growth of mold, mildew and fungus. Your system is bacteria and allergen free for clean and healthy air in your home.
Duct Armor® process to solve these problems:
· Video inspect your system for current condition
· Assess any damage and recommend restoration solutions
· Remove any debris and clean your air system
· Coat your duct work with our patented Duct Armor® product

Know the Facts Before You Decide to Convert to Overhead Air Ducts
Before you decided to abandon your underslab air ducts, keep these FACTS in mind when making a decision. The long term ramifications of your choice is very important.
When you have a counter-flow A/C system (i.e. air passing under the home's slab and through the attic duct work), the underground portion is composed of various materials - galvanized metal, cardboard sonotube, PVC pipe, or a combination of these. Sub-surface moisture has deteriorating effects on all three. Rust, termite damage, mold or mildew growth, and fungus all eventually invade and start destroying your underslab air system. When your underslab air system starts to deteriorate, you have two options: convert to an overhead system or restore the existing duct work.
Overhead conversion normally requires “capping” the floor vents with concrete which eliminates an “early warning” system for under slab flooding detection from all types of water leaks. These water issues can go undetected for days – weeks – months and can eventually lead to major slab and foundation damage. Slab damage can cause cracking of sheetrock, mold-mildew growth under your carpet, floor heaving, doors not closing properly, etc.
For proper overhead conversion, the under slab duct work MUST be FILLED completely with concrete to prevent flooding in the abandoned duct work. A true cost comparison between converting and restoring your underslab ducts must include properly filling in your underslab air ducts with concrete. Most conversion estimates do not include this cost because the technology has not been invented to completely and properly fill abandoned ductwork with concrete.
Restore the Duct Work
Sometimes this can be less expensive, sometimes more, or not possible because of advanced deterioration.

- Preserves the structural integrity of the slab and foundation
Sometimes less expensive, sometimes more, or not possible because of the home's design.
- Takes days or weeks to install
- Demolition and construction requires
- Huge loss of attic space
- Less energy efficient
- Makes your home less comfortable due to drafts
- No anti-mold properties
- May increase allergy issues
- Not original to your home & creates fur-downs throughout
- Puts your slab and foundation at risk
- Promotes condensation inside your overhead ductwork
